What are optional parameters in Python functions?
Optional parameters in Python functions allow you to define parameters that can be omitted when calling the function.
Can you give me an example of how to use optional parameters?
Sure! Here's a simple example:
def greet(name, greeting='Hello'):
return f'{greeting}, {name}!'
In this case, 'greeting' is an optional parameter.
What happens if I don't provide the optional parameter?
If you don't provide the optional parameter, the function will use the default value specified, which in this case is 'Hello'.
Can I have multiple optional parameters?
Yes, you can have multiple optional parameters in a function. Just make sure to provide default values for each.
